Subject: S/390: Improve result verification in test case vec-genmask-1.c.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7ab4f354570d0961c6be259ebe704f6f4563bb67;p=gcc.git

S/390: Improve result verification in test case vec-genmask-1.c.

THe attached patch improves checking of teh results of the subtests
"a" and "f".  As they share the same "vone" instruction, the duplicate
scan-assembler-times was bogus.  Moved "f" to a separate function to
fix this.  Also double check that no extra "vgmf" instructions are
used.

	* gcc.target/s390/zvector/vec-genmask-1.c: Improve result
